19、eword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a tech

20、nical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

21、 electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated t

22、o the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for

23、 identifying any or all such patent rights. ISO 21138-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including land drainage). ISO 21138 consists of the fo

28、age and sewerage Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) Part 1: Material specifications and performance criteria for pipes, fittings and system 1 Scope This part of ISO 21138 specifies the definitions and requirements fo

29、r pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems in the field of non-pressure underground systems for underground drainage and sewerage. NOTE 1 These pipes, fittings and the system can be use

30、d for highway drainage and surface water. This part of ISO 21138 specifically refers to PVC, PP and PE materials. NOTE 2 Other thermoplastic materials can be added via an addendum. This part of ISO 21138 covers a range of pipe and fitting sizes, materials, pipe constructions, nominal ring stiffnesse

31、s, and gives recommendations concerning colours. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjun

32、ction with ISO 21138-2 and ISO 21138-3, it is applicable to PVC-U, PP and PE structured-wall pipes and fittings, to their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for the transport of drainage and sewerage. It is

33、applicable to PVC-U, PP and PE structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints. NOTE 4 Pipes, fittings and other components conforming to any plastics product standards referred to in Clause 2 can be used with

34、 pipes and fittings conforming to this part of ISO 21138 when they conform to the requirements for joint dimensions given in Parts 2 and 3 of ISO 21138 and to the performance requirements given in Clause 9. NOTE 5 For dimensions larger than DN/OD 1200 or DN/ID 1200, this part of ISO 21138 can serve

35、as a general guide regarding appearance, colour, physical and mechanical characteristics as well as performance requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
